AW14X 53 structural steel [E = 29,000 ksi] section (see Appendix B for cross-sectional properties) is used as a column with an actual length of L= 16.0 ft. The column is fixed at its base and unrestrained at its upper end. Determine the maximum load P that may be supported by the column if a factor of safety of 1.8 with respect to buckling is specified. L. Part 1 Use Appendix B to look up the relevant area moment of inertia for buckling of the column. Answer: in.4

P.S. Use square rectangular hollow sections in Grade 355 steel. You will have to find the related section tables from the internet. Do not forget to refer to the related EN1993-1-1 tables and equations. Later, you will design the connections (the weld lengths, etc.) and the supports for this problem.
